I called up VEI systems and had them install their digital tach,speedo,water temp, and fuel gauges. I also ordered oil temp, oil pressure, boost pressure, Innovate wide band O2 from them. The wiring is really easy and Neil at VEI is really helpful and always answers my questions very quickly. I also just purchased, from a fellow hybridz member, megasquirt ECU and look to be installing that this weekend. Didn't really plan on getting megasquirt, but couldn't pass up the deal. Lots to learn about in so little time. Also purchased EDIS-6 system, but I will wait to install that. I am currently replacing my chassis harness with a painless wiring harness (Lots of fun, not). If I am lucky, I will install my new autopower roll bar. Very busy weekend.
